After years of free market reforms, Turkey's transition slowly begins to reverse. Islamist Abdullah Gul's candidacy as president in 2007 marks a clear shift away from secularist policies, and strains relations between the ruling AKP and the military. However, with broad support from both conservative Muslims and liberals, the AKP wins the parliamentary elections and Gul is elected president.

Then-Prime Minister Recep Tayyip Erdogan tables a constitutional reform increasing parliamentary control of the judiciary and army, effectively allowing the government to pick judges and senior military officials. The amendment, which is combined with measures also aimed at protecting child rights and the strengthening of the right to appeal, passed by a wide margin in a public referendum.

Pent-up anger directed by young people at Erdogan, Gul and the Islamist-rooted AKP hits a boiling point in May 2013. The violent police breakup of a small sit-in aimed at protecting Istanbul's Gezi Park spurs one of the fiercest anti-government protests in years. Eleven people are killed and more than 8,000 injured, before the demonstrations eventually peter out a month later.

A fragile ceasefire deal between the Turkish government and the Kurdish rebel PKK group breaks under the weight of tensions aggravated by the war in Syria. Military forces resume operations in the mostly Kurdish southeast of Turkey. In early 2016, the Kurdistan Freedom Hawks (TAK) — a breakaway PKK faction — claim responsibility for two bombings in Ankara, each killing 38 people.

A military coup attempt against the government shakes Turkey to its core and briefly turns the country into a war zone. Some 260 civilians die in overnight clashes with the army across five major cities. Erdogan, however, rallies supporters and the following morning rebel soldiers are ambushed by thousands of civilians on the Bosporus Bridge. The troops eventually drop their guns and surrender.

In the aftermath of the failed coup, Erdogan announces a state of emergency, leading to arrests of tens of thousands of suspected coup sympathizers and political opponents. Among those detained are military and judiciary officials and elected representatives from the pro-Kurdish HDP party. The purge is later expanded to include civil servants, university officials and teachers.

As part of Erdogan's crackdown against supposed "terrorist sympathizers," Turkey becomes one of the world's leading jailers of journalists, according to Reporters Without Borders. The government shuts down around 110 media outlets in the year following the coup and imprisons more than 100 journalists, including German-Turkish correspondent Deniz Yücel.

With a referendum on expanding Erdogan's presidential powers set for April 2016, AKP officials look to galvanize support among Turks living in Europe, particularly in Germany and the Netherlands. However, the Netherlands forbids Turkish Foreign Minister Mevlut Cavusoglu from landing in the country, while Germany opts to cancel two rallies. Erdogan accuses both countries of Nazi-style repression.

Erdogan narrowly wins the referendum vote expanding his power. As a result, Turkey's parliamentary system is abolished in favor of a strong executive presidency. Erdogan is also allowed to remain in power potentially until 2029. However, international election monitors claim that opposition voices were muzzled and that media coverage was dominated by figures from the "yes" campaign.

Erdogan secures a new five-year term and sweeping new executive powers after winning landmark elections on June 24. His AKP and their nationalist allies also win a majority in parliament. International observers criticize the vote, saying media coverage and emergency measures gave Erdogan and the AKP an "undue advantage" in the vote.

In Turkey and abroad, Recep Tayyip Erdogan has a polarizing effect. He has been described as a neo-Ottoman "sultan" as well as an authoritarian leader. From his early beginnings campaigning for Islamist causes to leading NATO's second largest military as the president of Turkey, DW explores the rise of the Turkish leader.

After years of moving up the ranks of the Islamist-rooted Welfare Party, Erdogan was elected mayor of Istanbul in 1994. But four years later, the party was ruled unconstitutional on the grounds it threatened Turkey's secularist nature, and was disbanded. He was later jailed for four months for a controversial public reading of a poem, and consequently lost his mayorship over the conviction.

Erdogan co-founded the Justice and Development Party (AKP), which won a majority of seats in 2002. He was made prime minister in 2003. During his first years in office, Erdogan worked on providing social services, improving the economy and implementing democratic reforms. But some have argued that his premiership was also marked by a religious shift in the political sphere.

While Turkey's constitution guarantees the country's secular nature, observers believe Erdogan has managed to purge the "old secularist guard." The Turkish leader has said that one of his goals is to raise a "pious generation." Erdogan's supporters have hailed the Turkish leader's initiatives, arguing that they've reversed years of discrimination against practicing Muslims.

In July 2016, a failed military coup targeting Erdogan and his government left more than 200 people dead, including civilians and soldiers. In the wake of the coup attempt, Erdogan declared a state of emergency and vowed to "clean up" the military. "In Turkey, armed forces are not governing the state or leading the state. They cannot," he said.

Since the failed coup, authorities have launched a nationwide crackdown, arresting more than 50,000 people in the armed forces, police, judiciary, schools and media. Erdogan has blamed Fethullah Gulen, a self-exiled cleric in the US and former ally, and his supporters of trying to undermine the government. But rights groups believe the allegations are a means to solidify his power and influence.

While Erdogan enjoys significant support in Turkey and the Turkish expatriate community, he has been criticized for his heavy-handed policies and military campaigns against Kurdish militants following the collapse of a peace process in 2015. This January, Erdogan launched a deadly offensive into the northern Syrian enclave of Afrin, an operation that was widely condemned by human rights groups.

Having served as Turkey's president since 2014, Erdogan successfully extended his time in office after winning elections in June. The elections marked Turkey's transition to an executive-style presidency. Observers believe the elections will herald a new era for Turkey – for better or worse.
